Abstract: A device for shaping containers by folding cardboard sheets, comprising a folding station for folding cardboard sheets, provided with a die; a handling station for handling said sheets from a store to said folding station, with a frame and at least one gripping head that can be moved on the frame and comprises means for grasping and holding said sheet, and also a punch with a complementary shape so as to interact with the inside of said die. The punch comprises a bearing surface for bearing against the bottom of said grasped sheet. The grasping means is mounted so as to be able to move relative to said punch and free to move in at least one plane parallel to said bearing surface. The invention also relates to a corresponding shaping method.

Abstract: The present invention relates to a retention device for a product which is compatible with a plurality of different shapes of products, within an industrial line for producing and processing products, comprising a frame with a receiving base which is intended to support the bottom of a product; a gripping means for a product comprising a set of pincers which is provided with two jaws which can be moved between a spaced-apart position and a closed-up position. Each jaw is mounted freely in terms of rotation about a pivot point and has a concave vertical shape in order to retain the product at least at one upper support location and at least at one lower support location. The invention also relates to a conveying installation for products within an industrial line for producing and processing products, comprising at least one retention device according to the invention.

Abstract: A battery element includes series-connected electrochemical accumulators applying a difference in potential between first and second poles, two power output terminals, and a securing device. The securing device comprises first and second switches connected in series between the first and second poles. The first switch is a normally-closed switch, and the second switch is a normally-open switch. The normally-open second switch is configured to selectively isolate/connect the first pole and the first terminal, and the normally-closed first switch being configured to selectively isolate/connect the first and second terminals. The electrochemical accumulators are configured to apply a voltage as a control signal for the normally closed first switch.

Abstract: A power battery having electrochemical accumulators connected in series between two output terminals (B1, B2). There is a switch allowing one of the output terminals to be selectively isolated from an electrical load. There is a detection circuit for detecting an external short-circuit, to which the voltage between the output terminals of the battery is applied. The detection circuit is configured to compare the applied voltage to a voltage threshold representative of a short-circuit and to generate a signal for opening said switch when the applied voltage drops below the threshold.
